DETAILED DESCRIPTION

The present disclosure is to be further described clearly andcomprehensively by referring to appended figures and embodiments.Described embodiments herein are only a part of, but not all of, thepossible embodiments. Based on the described embodiments of the presentdisclosure, those having ordinary skill in the art may obtain otherembodiments without contributing creative endeavor, which should bewithin the scope of the present disclosure.

Referring to FIG. 1, an electronic atomization device 1 may be provided.Some components of the electronic atomization device may be heated by anelectric current to steam aerosol-generating substrate to generate asmoke, and may be a device for atomization. The aerosol-generatingsubstrate can be heated and vaporized to generate aerosol or smoke. Inthis embodiment, the aerosol-generating substrate may be a liquid. Thecomponents of the electronic atomization device 1 for atomizing theliquid may be an atomizer as shown in FIG. 2. Referring to FIG. 2 andFIG. 3, an atomizer of an embodiment of the present disclosure mayinclude: a shell 11, a heating assembly 12, a lid 13, a base 14, and afirst member 15.

The shell 11 may define a liquid cavity 111 to store a liquid, and asmoke outlet 112. The heating assembly 12 may be arranged to heat theliquid stored in the liquid cavity 111 and atomize the liquid togenerate a smoke. For example, when the liquid in the liquid cavity 111flows to reach the heating assembly 12, the liquid may be heated andatomized to generate the smoke. The generated smoke may flow through thesmoke outlet 112 to reach a user to be inhaled.

In the present embodiment, the heating assembly 12 may be engagedbetween the lid 13 and the base 14, wherein the lid 13 and the base 14may be fixed with respect to each other, such that the heating assembly12 may be fixedly arranged between the lid 13 and the base 14. The lid13 may define a liquid inlet 131 a, and the liquid inlet 131 a maycommunicate with the liquid cavity 111. The liquid in the liquid cavity111 may flow through the liquid inlet 131 a to reach the heatingassembly 12. The atomizer may further define an air entering hole 14 ato allow external air to enter the atomizer. For example, the base 14may define the air entering hole 14 a, communicating with an external,such that the external air may enter the atomizer through the airentering hole 14 a, driving the smoke to flow into the smoke outlet 112.

In the present embodiment, the first sealing member 15 may be arrangedbetween the lid 13 and the heating assembly 12, contacting the lid 13and the heating assembly 12 at the same time for sealing. In such a way,when the liquid flows from the liquid cavity 111 through the liquidinlet 131 a to the heating assembly 12, the liquid may not be leakedfrom a position at which the lid 13 contacts or connects with theheating assembly 12. In other words, the first sealing member 15 mayseal the connected or contact position between the lid 13 and theheating assembly 12. Further referring to FIG. 3, an air guiding channel16 may be defined between the first sealing member 15 and the heatingassembly 12. The air guiding channel 16 may at least guide the externalair entering from the air entering hole 14 a to the liquid cavity 111.To be specific, the external air may enter the base 14 through the airentering hole 14 a, and flow into the air guiding channel 16, furtherflowing through the liquid inlet 131 a entering the liquid cavity 111.

According to the present embodiment, the liquid in the liquid cavity 111may flow through the liquid inlet 131 a of the lid 13 to reach theheating assembly 12. The heating assembly 12 may heat and atomize theliquid to generate the smoke. With a pressure generated by a user whileinhaling, air may enter the atomizer from the base 14 through the airentering hole 14 a. The pressure may create air flow, driving the smoketo flow into the smoke outlet 112, and the smoke may be inhaled by theuser.

In the related art, as the liquid may continuously flow to the heatingassembly 12 for atomization, a pressure in the liquid cavity 111 may bereduced to become a negative pressure. Therefore, flowing of the liquidto the heating assembly 12 for atomization may be blocked, resulting inan obstructed downward flow of the liquid. Also, the liquid which isalready on the heating assembly 12 may not be able to flow, such that aburnt taste may be generated, impacting user experience. In order tosolve the technical problem, the present disclosure may provide a firstsealing member 15 between the lid 13 and the heating assembly 12, and anair guiding channel 16 may be defined between the first sealing member15 and the heating assembly 12. The air guiding channel 16 may at leastguide the air entering from the air entering hole 14 a to the liquidcavity 111 to increase the pressure inside the liquid cavity 111, suchthat the liquid in the liquid cavity 111 may not be blocked from flowingdownward, increasing efficiency of the atomizer and improving userexperience.

In the present embodiment, the shell 11 may be provided to define ahollow tube, of which the shape may be designed according to actualdemands of the electronic atomization device, such as a cylinder orelliptic cylinder shape. The smoke outlet 112 may also be defined astubular, extending along a length direction of the shell 11. An end ofthe smoke outlet 112 may communicate with a smoke vent defined by amouthpiece 11 a, and the other end of the smoke outlet 112 receiving thesmoke generated by the heating assembly 12. The liquid cavity 111 may bedefined between an outer side wall of the smoke outlet 112 and an innerside wall of the shell 11, and may store the liquid. Further, the shell11 may define a pouring hole (not shown in the figure) for liquid to beadded, wherein the pouring hole may communicate with the liquid cavity111. The pouring hole may be sealed while not in use. Alternatively,along a direction starting from the mouthpiece 11 a to the heatingassembly 12, a width of the shell 11 may increase gradually at thebeginning and then maintain when reaching a certain width. In otherembodiments, the air entering hole 14 a may be defined on the mouthpiece11 a and further communicate with the smoke outlet 112. In such a way,when the user inhales, pressure may be generated, allowing external airto enter the smoke outlet 112 through the air entering hole 14 a,forming an air flow to drive the smoke to flow.

Referring to FIG. 2 and FIG. 4, alternatively, the heating assembly 12may include a porous ceramic liquid guiding member 121 and a heatingmember 122, mounted on a bottom face 121 b of the porous ceramic liquidguiding member 121. The porous ceramic liquid guiding member 121 may bemade of a ceramic material having a plurality of pores, wherein theceramic may contain aggregates, binders, and pore-forming agents, andundergo a sintering process. A plurality of pores may be defined withinthe ceramic, communicating with each other and with surfaces of theceramic. The ceramic may have high porosity, be chemically stable, andhave a large specific surface area, a small volumetric density, a lowthermal conductivity, corrosion and thermal resistance. In the presentembodiment, defining the air guiding channel 16 further allowsventilation of the smoke while flowing through a bending-structuredporous liquid guiding member 121, such that the burnt taste due to theobstructed downward flow of the liquid may be reduced, increasingefficiency of the atomizer and improving user experience.

To be specific, the porous ceramic liquid guiding member 121 may definea liquid guiding groove 1211. For example, the porous ceramic liquidguiding member 121 may have a top face 121 a facing the liquid cavity111, and the top face 121 a may be embedded inwards to define the liquidguiding groove 1211. The liquid flowing through the liquid inlet 131 amay be received in the liquid guiding groove 1211. The liquid guidinggroove 1211 may have a plurality of cross surfaces parallel with the topface 121 a of the porous ceramic liquid guiding member 121, an area ofeach of the plurality of cross surfaces may decrease gradually along adepth direction starting from the bottom face 121 b towards the top face121 a of the porous ceramic liquid guiding member 121. By defining theliquid guiding groove 1211, the liquid may be easily received, and acontact area between the liquid and the porous ceramic liquid guidingmember 121 may be improved, thus, increasing flowing efficiency and aflowing speed of the liquid.

In the present embodiment, the heating member 122 may comprise at leastone of the following: a heating coating, a heating circuitry, a heatingplate or a heating net. To be specific, the heating member 122 may beprovided on the bottom face 121 b of the porous ceramic liquid guidingmember 121, wherein the bottom face 121 b is opposite to the liquidguiding groove 1211. The liquid may flow through the porous structure ofthe ceramic liquid guiding member 121, reaching the heating member 122at the bottom face 121 b, wherein the heating member 122 may beconnected to a power to heat and atomize the liquid, generating thesmoke. In the present embodiment, the heating member 122 may be aheating resistance wire. After the heating member 122 is connected tothe power to be heated, the liquid flowing through the porous ceramicliquid guiding member 121 reaching the bottom face 121 b may be atomizedto generate the smoke. In the present embodiment, the heating member 122may be twisted and turned.

The guidingportion 131 may define the liquid inlet 131 a, and the liquid inlet 131a may extend through the guiding portion from a top 1311 to a bottom1312. In the present embodiment, two of the liquid inlets 131 a may bedefined spaced apart from each other, and each of the two liquid inlets131 a may communicate with each of two liquid cavities 111, wherein thetwo liquid cavities 111 may be defined at two sides of the smoke outlet112. The liquid inlet 131 a may communicate with the liquid cavity 111at the top 1311 of the guiding portion 131, and further communicate withthe liquid guiding groove 1211 at the bottom 1312 of the guiding portion131. The liquid inlet 131 a may be elliptical, and areas of crosssurfaces of the liquid inlet 131 a may decrease gradually along adirection starting from the top 1311 towards the bottom 1312. In thepresent disclosure, the lid 13 may be manufactured as an integralcomponent.

Referring to FIG. 2 to FIG. 4, in the present embodiment, a side wall ofthe housing portion 132 may extend from an outer edge of the bottom 1312of the guiding portion 131 to define a chamber 1321. Distance betweenthe side wall of the housing portion 132 and periphery of the liquidinlet 131 a may be greater than 0, wherein the liquid inlet 131 a may bedefined at the bottom 1312 of the guiding portion 131, That is, due todistance between an inner surface (facing the chamber 1321) of the sidewall of the housing portion 132 and the periphery of the liquid inlet131 a being greater than 0, for example, the distance may be equal to0.3 mm, a portion of the bottom 1312 may be between the side wall of thehousing portion 132 and the periphery of the liquid inlet 131 a, and maybe capable of abutting against the first sealing member 15 for sealing.This is to ensure the sealing effect of the first sealing member 15 andavoiding leakage of the liquid. The chamber 1321 may receive a portionof the heating assembly 12. The first sealing member 15 may be receivedin the chamber 1321, supporting the guiding portion 131 and the heatingassembly 12 for sealing.

Alternatively, the guiding portion 131 may further define an air outlet131 b at the top 1311. In the present embodiment, the air outlet 131 bmay be defined adjacent to the liquid inlet 131 a, and spaced apart fromthe liquid inlet 131 a. The guiding portion 131 may further define athrough hole 131 c, wherein the through hole 131 c may extend throughtwo opposing side surfaces 1313 of the guiding portion 131. In thepresent embodiment, one of the side surfaces 1313 of the guiding portion131 may be a surface non-adjacent to a side wall 142 of the base 14.

Further,when the second sealing member 17 encases the lid 13 for sealing, it mayalso seal a gap between the side wall of the smoke outlet 112 and theside wall of air outlet 131 b. In such a way, a possibility of theliquid being leaked from the air outlet may be reduced, and apossibility of smoke leaking may be reduced. In the present embodiment,the second sealing member 17 may be made of silicone as an integralcomponent.

Referring to FIG. 2 and FIG. 4, alternatively, the base 14 may include abottom wall 141 and a side wall 142 connecting with the bottom wall 141.For example, there may be two side walls 142 arranged oppositely andspaced apart from each other.

When the lid 13 is received in the receiving space 140of the base 14 and fix with the two side walls, the support stages 1421may support the housing portion 132 of the lid 13. For example, when thefirst sealing member 15 encases the porous ceramic liquid guiding member121, and when the porous ceramic liquid guiding member 121 is fixedbetween the lid 13 and the base 14, an end of the first sealing member15 may be arranged between the top face 121 a of the porous ceramicliquid guiding member 121 and the bottom 1312 of the guiding portion131, and the other end of the first sealing member 15 may further bearranged between the support stages 1421 and the porous ceramic liquidguiding member 121, to achieve the sealing. In the present embodiment,the first sealing member 15 may be made of silicone or the like, andformed as an integral component.

A first situation of the air guiding channel 16 of the presentembodiment may be described herein.

Referring to FIG. 2 to FIG. 5, alternatively, the first sealing member15 may include a top wall 151, arranged to surround the liquid guidinggroove 1211, encasing the top face of the porous ceramic liquid guidingmember 121, and supporting the lid 13, but the liquid guiding groove1211 may be exposed. A bottom face of the top wall 151, facing theporous ceramic liquid guiding member 121, and the porous ceramic liquidguiding member 121 may define the air guiding channel 16. For example,the bottom face of the top wall 151 may be a gasket, surrounding theliquid guiding groove 1211 and contacting the top face of the porousceramic liquid guiding member 121.

Referring to FIG. 5, alternatively, the bottom face of the top wall 151facing the porous ceramic liquid guiding member 121 may define a firstair guiding recess 1511. When the first sealing member 15 is engagedwith the porous ceramic liquid guiding member 121, the top face 121 a ofthe porous ceramic liquid guiding member 121 may support the bottom faceof the top wall 151, therefore, the first air guiding recess 1511 mayfunction as the air guiding channel 16. In order to define the airguiding channel 16, the bottom face of the top wall 151, facing theporous ceramic liquid guiding member 121, may define at least one of thefirst air guiding recesses 1511, which may be striped recesses. When thefirst sealing member 15 seals the porous ceramic liquid guiding member121, there may be gaps between the inner side face of the top wall 151and the top face 121 a of the porous ceramic liquid guiding member 121,wherein the gaps may function as the air guiding channels 16. The airentering from the air entering hole 14 a of the base 14 may flow alongthe air guiding channel 16 to reach the liquid inlet 131 a defined onthe lid 13, further reaching the liquid cavity 111, to balance the innerpressure of the liquid cavity 111 with the outside, such that liquid maybe prevented from being obstructed.

Alternatively, a depth D of the first air guiding recess 1511 may be 0.1mm-0.3 mm. Alternatively, the depth D of the first air guiding recess1511 may be 0.15 mm-0.25 mm. Alternatively, a width H of the first airguiding recess 1511 may be 0.5 mm-1 mm. Alternatively, the width H ofthe first air guiding recess 1511 may be 0.7 mm-0.8 mm. In the presentembodiment, the depth D may refer to a distance between a side wall ofthe first air guiding recess 1511, facing the bottom face of the topwall 151, and the bottom face of the top wall 151. The width H of thefirst air guiding recess 1511 may refer to a distance between twoopposite side walls of the first air guiding recess 1511, and both ofthe two opposite side walls of the first air guiding recess areperpendicular to the bottom face of the top wall 151. By defining thefirst air guiding recess 1511 with such depth D and such width H, theair guiding channel 16 may be defined to allow the air to flow, suchthat leakage of the liquid may be reduced.

On the basis of the first situation, the first sealing member 15 may befurther described hereafter, and a second situation of the air guidingchannel 16 of the present embodiment may also be described.

The tube wall 11 a may define a liquid cavity 1101 for storing a liquid.The heating assembly 120 may be arranged to atomize the liquid flowingfrom the liquid cavity 1101 to generate the smoke. For example, theliquid cavity 1101 and a space defined by the heating assembly 120 maybe communicated. Therefore, the liquid stored in the liquid cavity 1101may flow to reach the heating assembly 120, and the heating assembly 120may be heated by electric current to atomize the liquid, generating thesmoke. The first sealing member 180 may be arranged between the tubewall 11 a and the heating assembly 120 for sealing. This is to reduce apossibility of the liquid leaking from a gap between the liquid cavity1101 and the heating assembly 120 during flowing. In the presentembodiment, an air guiding channel 10 may be defined between the firstsealing member 180 and the tube wall 11 a, and the first sealing membermay achieve the sealing and, at the same time, guide air to flow intothe liquid cavity 1101.

According to the present embodiment, by defining the air guiding channelbetween the first sealing member 180 and the tube wall 11 a, the air maybe easily guided to reach the liquid cavity 1101, such that pressureinside the liquid cavity 1101 may be balanced with an outside, andobstructed flow of the liquid caused by negative pressure of the liquidcavity 1101 may be solved, improving user experience and simplifying astructure of the atomizer.

Thetube wall 11 a may define the liquid cavity 1101, a smoke outlet 1101,and an air entering channel 1103, wherein each of the liquid cavity1101, the smoke outlet 1101, and the air entering channel 1103 mayextend along a length direction of the tube wall 11 a. The liquid cavity1101, the smoke outlet 1101, and the air entering channel 1103 may bedefined spaced apart from each other, for example, they are notcommunicated directly within the tube wall 11 a.

For example, the tube wall 11 a may include a first tube wall 115 andtwo second tube walls 113. The first tube wall 115 may define a liquidcavity 1101. Each of the two second tube walls 113 may be bent at oneend, and connected to the first tube wall 115 at the bent end. One ofthe two second tube walls 113 may be connected to a side of the firsttube wall 115 to define the smoke outlet 1102, and the other of the twosecond tube walls 113 may be connected to an opposing side of the firsttube wall 115 to define the air entering channel 1103. In the presentembodiment, the air entering channel 1103 may be defined to guide theexternal air to flow to a position at which the heating assembly 120 islocated, and an air flow generated by the external air may drive thesmoke generated by the heating assembly 120 to flow into the smokeoutlet 1102, such that the smoke may be guided to flow through the smokeoutlet 1102 to reach a component, such as a mouthpiece, and may beinhaled by the user.

For example, the atomizer 310 may further define an air entering hole100 communicating with the air entering channel 1103. The air out of theatomizer 301 may enter the air entering channel 1103 through the airentering hole 100.

The first tube wall 115 maybe arranged between the smoke outlet 1102 and the liquid cavity 1101,such that the smoke outlet 1102 and the liquid cavity 1101 are notdirectly communicated. The first tube wall 115 may further be arrangedbetween the liquid cavity 1101 and the air entering channel 1103, suchthat the liquid cavity 1101 and the air entering channel 1103 are notdirectly communicated. Alternatively, the tube wall 11 a may bemanufactured as an integral component, and that is the first tube wall115 and the two second tube walls 113 may be an integral component. Inthe present embodiment, along the length direction of the tube wall 11a, a length for which the second tube wall 113 extends may be greaterthan a length for which the first tube wall 115 extends.

In the present embodiment, the heating assembly 120 may be partiallyreceived in a space defined by the first tube wall 115. For example, theheating assembly 120 may be embedded into an end of the liquid cavity1101. The first sealing member 180 may abut against an inner surface ofthe first tube wall 115 and an outer surface of the heating assembly 120for sealing. An air guiding channel 10 may be defined between the firstsealing member 180 and the first tube wall 115. For example, aprotrusion may be arranged on the inner surface of the first tube wall115 facing towards the heating assembly 120, alternatively, a recess maybe defined in the inner surface of the first tube wall 115 facingtowards the heating assembly 120. When the first sealing member 180abuts against the inner surface of the first tube wall 115, a gap may bedefined between the first sealing member 180 and the first tube wall 115due to the protrusion or the recess, and the gap may function as the airguiding channel 10.

Alternatively, the entire heating assembly 120 may be arranged beneaththe first tube wall 115, and the first sealing member 180 may bearranged to be various shapes, with a proviso that the liquid cavity1101 communicates with the space defined by the heating assembly 120. Inthe present embodiment, the first sealing member 180 may abut betweenthe first tube wall 115 and the heating assembly 120 for sealing, andthe air guiding channel 10 may be defined by arranging the protrusion ordefining the recess between the first sealing member 180 and the firsttube wall 115.

As shown in FIGS. 14 to 16, in the present embodiment, the inner surfaceof the first tube wall 115 facing towards the heating assembly 120 maybe arranged with a plurality of first convex ribs 1150, wherein theplurality of first convex ribs 1150 may protrude from the inner surfaceof the first tube wall 115. When the first sealing member 180 abutsagainst the plurality of first convex ribs 1150, the air guiding channel10 may be defined between the inner surface of the first tube wall 115and the first sealing member 180. To be specific, when the first sealingmember 180 abuts against the inner surface of the first tube wall 115,as the plurality of first convex ribs 1150 protrudes from the innersurface of the first tube wall 115, a gap may be defined between each ofthe plurality of first convex ribs 1150, and the gap may serve as theair guiding channel 10.

Alternatively, as shown in FIG. 13 and FIG. 15, the inner surface of thefirst tube wall 115 facing towards the heating assembly 120 may bearranged with a flange 116 along a circumferential direction. The flange116 may be arranged to abut against the heating assembly 120, and mayallow the sealing between the flange 116 and the heating assembly 120.The first sealing member 180 may be clamped between the flange 116 andthe heating assembly 120, and contact the flange 116 and the heatingassembly 120 at the same time for sealing, such that the liquid may beprotected from leaking during flowing from the liquid cavity 1101 to theheating assembly 120. In the present embodiment, the flange 116 may beformed on the inner surface of the first tube wall 115, and the flange116 and the first tube wall 115 may be an integral component. In otherembodiments, the tube wall 11 a including the second tube wall 113, thefirst tube wall 115, and the flange 116 may not be an integralcomponent. The flange 116 may be arranged on the inner surface of thefirst tube wall 115 in a detachable manner. An outer edge of the flange116 may define a hole, and that means a middle portion of the flange 116may be porous, such that the liquid may flow from the liquid cavity 1101through the hole to reach the heating assembly 120. In the presentembodiment, the air guiding channel 10 may be defined between the firstsealing member 180 and the inner surface of the first tube wall 115, anddefined between the first sealing member 180 and the flange 116. In thepresent embodiment, the external air may enter the liquid cavity 1101through the air guiding channel 10, such that, to some extent, thepressure inside the liquid cavity 1101 may be balanced with the outsideof the liquid cavity 1101.

In the present embodiment, when the atomizer 301 is working, forexample, when a user is inhaling, the inhalation may generate apressure, and the pressure may enable the air to enter the atomizer 301through the air entering hole 100, generating an air flow inside theatomizer 301. The liquid may flow to the heating assembly 120 and may beatomized to generate the smoke. The smoke may be driven by the air flowto flow into the smoke outlet 1102 and reach the user to be inhaled. Asthe air guiding channel 10 may guide the air to flow into the liquidcavity 1101. A pressure difference between the inside and the outside ofthe liquid cavity 1101 may be decreased, such that a negative pressuregenerated due to consumption of the liquid stored in the liquid cavity1101 may be reduced, and the liquid may flow downwards smoothly, and aburnt taste of the electronic atomization device may be reduced,improving user experience.

As shown in FIG. 13, alternatively, the flange 116 may protrude towardsa direction perpendicular to the inner surface of the first tube wall115, wherein the inner surface is facing towards the heating assembly120, or the flange 116 may protrude towards a direction perpendicular tothe length direction of the tube wall 11 a.

As shown in FIG. 15 and FIG. 16, alternatively, the flange 116 may bearranged with a plurality of second convex ribs 1160 on a surface of theflange 116 facing towards the first sealing member 180. The plurality ofsecond convex ribs 1160 may be spaced apart from each other and arrangedto protrude from the surface of the flange 116. When the first sealingmember 180 abuts against the plurality of second convex ribs 1160,protrusion of the plurality of second convex ribs 1160 allows theplurality of second convex ribs 1160 to have a height, the height allowsa gap to be defined between the flange 116 and the first sealing member180, and the gap may at least be defined near the plurality of firstconvex ribs 1150. As the first sealing member 180 abuts against theflange 116, the inner surface of the first tube wall 115, and theheating assembly 120, gaps defined near the plurality of first convexribs 1150 and near the plurality of second convex ribs 1160 may beinter-communicated, and the gaps may serve as the air guiding channel10. In such a way, the air may smoothly flow into the liquid cavity 1101through the air guiding channel 10.

In the present embodiment, the plurality of first convex ribs 1150 andthe plurality of second convex ribs 1160 may be formed on the tube wall11 a as an integral component. Protrusion of the plurality of firstconvex ribs 1150 from the inner surface of the first tube wall 115 andprotrusion of the plurality of second convex ribs 1160 from the flange116 may be easily molded together with the tube wall 11 a.

The first sealing member180 may contact the inner surface of the first tube wall 115 and theflange 116 at the same time, such that the first tube wall 115 may besealed with the heating assembly 120 effectively. Due to the height ofthe plurality of first convex ribs 1150, a gap may be defined betweenthe first sealing member 180 and the inner surface of the first tubewall 115, the gap may at least be defined near the plurality of firstconvex ribs 1150. By arranging the plurality of first convex ribs 1150and the plurality of second convex ribs 1160 cooperatively, the gapdefined between the first sealing member 180 and the inner surface ofthe first tube wall 115 facing towards the heating assembly 120 and thegap defined between the first sealing member 180 and the flange 116 mayserve as the air guiding channel 10. The air may smoothly enter theliquid cavity 1101 through the air guiding channel 10. According to thepresent embodiment, by arranging the plurality of first convex ribs 1150and the plurality of second convex ribs 1160, the air guiding channel 10may be defined effectively, such that the air may smoothly enter theliquid cavity 10, the pressure inside the liquid cavity 1101 may bebalanced with the outside, and a possibility of obstructed liquid flowmay be reduced.

Further referring to FIG. 15 and FIG. 16, alternatively, an end of the asecond convex rib 1160 may extend to the outer edge of the flange 116,and an opposing end of the second convex rib 1160 may extend to anintersection at which the flange 116 is connected to the first tube wall115. For example, the second convex rib 1160 may be substantiallylinear. An end of a first convex rib 1150 may be connected to theopposing end of the second convex rib 1160, and an opposing end of thefirst convex rib 1150 may extend an edge of the first tube wall 115close to the heating assembly 120. The first convex rib 1150 may besubstantially linear. In the present embodiment, the second convex rib1160 may be connected to the first convex rib 1150, such that the airmay flow along the air guiding channel 10 more smoothly. In otherembodiments, a shape of the second convex rib 1160 and a shape of thefirst convex rib 1150 may be curved or arched, and will not be limited.In other embodiments, the second convex rib 1160 and the first convexrib 1150 may be arranged spaced apart from each other.
